Lemon Tree Leaves
Some of the leaves on our lemon tree have patchy yellow on the leaves and the leaf is fairly pale green. A lot of new leaves and virtually no scale. Tree is in a 1/2 wine barrel.

It sounds like you may have a pest problem, likely mites, which can be hard to see. I would treat the plant with a pesticide and a mitecide. Neem oil is good because it is both a pesticide and a mitecide plus it is organic.
